54. On the Lord's day, signifies Divine influx then. This is evident from the signification of "the Lord's day," as being then the Lord is instructing man, thus when He is flowing in. The Lord's day is the day of the Sabbath, and the Sabbath in the ancient churches, which were representative churches, was the most holy thing of worship, because it signified the union of the Divine and the Human in the Lord, and thence also the conjunction of His Divine Human with heaven (see Arcana Coelestia, n. 8494-8495, 10356, 10360, 10370, 10374, 10668). But when the Lord had united His Divine with His Human that holy representative ceased, and that day became a day of instruction (n. 10360). For this reason revelation was made to John on the Lord's day. Revelation here is instruction concerning the state of the church.
